The IRS Get My Payment (https://www.irs.gov/coronavirus/get-my-payment) tool will provide you the status of your payment, including the date it is scheduled to be deposited into your bank account or mailed to you.
An additional feature of the Get My Payment tool will allow you a chance to provide your bank account information to receive your payment more quickly rather than waiting for a paper check. This feature will be unavailable if the Economic Impact Payment has already been scheduled for delivery.
